From the book "Elements of Style," if two clauses have the same subject and joined by the conjunction "and" then we do not use the subject in the second clause.
e.g., He has had several years' experience and is thoroughly competent
What if there are more than 2 clauses, does the above rule hold good?
For example, is the following sentence correct?
In 2015 I didn't have the courage to participate, in 2016 couldn't clear the preliminary round, and in 2017 was among the 10 finalists.
Also, can the readability by increased by rephrasing or with better punctuation?
